Definitions

  • the invention relates to a radiator connection fitting with a housing that has a supply channel arrangement with a flow channel and a return channel and one Radiator duct arrangement with an outlet duct and has an input channel, between the supply channel arrangement and the radiator duct assembly at least one valve with valve seat and closing element is arranged and all channels have central axes.
  • the invention further relates to a radiator with a Radiator connection fitting.
  • the connection fitting is often due to its appearance also called H-piece.
  • the supply channel arrangement is here with a building-fixed pipe system connected via the heating fluid to and can be dissipated.
  • the output channel of the radiator channel arrangement is with a connecting piece of the Radiator connected over the heating fluid in the radiator is fed.
  • Another connection piece of the radiator through which the heating fluid flows out, is with the input channel of the radiator channel arrangement connected.
  • the channels of the radiator channel arrangement and the channels of the supply channel arrangement can for example by 180 ° or 90 ° to each other be staggered. In exceptional cases other angular positions are also possible.
  • the valve is arranged for control the amount of heating fluid required is usually provided oblique holes, so that there is a cable routing inside the housing results, which creates space for the valve seat.
  • oblique holes can also other housing designs be provided. These housing designs, for example projections or partitions inside the Housing, make the manufacture of such a fitting complicated.
  • the invention has for its object the manufacture to simplify a radiator connection fitting.
  • This task is done with a radiator connection fitting of the type mentioned in that the central axes all channels laterally offset from each other are.
  • the channels can be easily created by drilling.
  • the lateral offset creates space in which one can arrange the valve seat.
  • the holes can all have the same orientation, i.e. H. you can do that Drill holes in the housing without the alignment change the housing to a drilling spindle have to. It may only be necessary that one the housing twisted about its longitudinal axis to drill holes from different sides. Such However, handling is far easier than that precise setting of predetermined angular positions.
  • the term "bores" is not intended to be the design limited to the manufacturing process of drilling.
  • the holes can also be created by other measures become.
  • the central axes of all channels are arranged in planes are perpendicular to a longitudinal axis of the housing stand.
  • the channels are not just parallel to each other arranged or arranged in parallel planes, they are also perpendicular to the housing. This simplifies it manufacturing continues.
  • the housing only needs to be in the appropriate alignment to the drilling spindle become. Such a clamping of the housing is possible without any problems.
  • the channels are so far against each other offset that between opposing opening cross sections a predetermined distance remains.
  • the depth of the bores, that form the channels a lower accuracy requirement posed. It is entirely permissible that channels that will later work together in Overlap lengthwise.
  • the valve seat is preferably arranged at a distance.
  • the valve seat can be stepped Reduction of the cross section of the connecting channel be formed. This ensures that the closing element always only perpendicular to the valve seat can be moved. This results in a good tightness and a relatively long lifespan.
  • the channels preferably expand at least one Channel arrangement for connection openings. This makes it easier the assembly of the valve.
  • the lines leading to the channels just have to belong in the connection openings be put in. Also the manufacture of the valve is simplified because there are no complicated connection geometries have to be manufactured.
  • connection openings are smooth inside and a fastener for radiator connections outside the connection openings is provided.
  • the Establishment of a conduit path for the heating fluid is caused by the corresponding Line or the corresponding connection in the connection openings is inserted.
  • the tightness can between the line and the connection openings be brought about by appropriate seals.
  • the attachment the line or the connection is made with the fastening device.
  • the fastener on the other hand, it no longer has to be designed that it is itself liquid-tight.
  • the fastening device advantageously has a clamping plate with the help of a clamping device parallel to the central axes of the channels of the radiator channel arrangement is movable towards the housing.
  • This clamping plate has two functions. On the one hand it holds the corresponding connection piece or that Cable end firmly in the housing. On the other hand, it serves but also a certain clamping force during assembly to generate, for example, for improvement the sealing effect can be used.
  • the tensioning device is advantageously a screw trained with a thread in the clamping plate is engaged.
  • Such a tensioning device is particularly simple.
  • the gear ratio the screw still allows that relatively large forces for tightening the connecting piece or of the line end can be applied.
  • the fastening device in a predetermined angular range with respect to the housing is inclinable.
  • the connecting pieces are not exactly the same on a radiator long, but they differ by a few millimeters. Now if you allow the fastener can tilt something, then plays one of these No inaccuracy in the manufacture of the radiator bigger roll more because of the fastener can be compensated. The same applies of course also for the ends of the heating system, if this with a little difference from the wall or stick out of the floor.
  • connection openings are arranged. It says on the one hand enough space is available, on the other hand it is possible with a single fastening device both connection openings and the connection pieces inserted into them or secure cable ends. Outside the connection openings are not additional measures more needed. This simplifies production.
  • the task is for a radiator of the type mentioned Art solved in that two connecting pieces of the radiator in the connection openings of the radiator duct arrangement are plugged in.
  • connection piece is between the outer wall and the inner wall of the connection openings each arranged at least one sealing ring.
  • This sealing ring then forms the seal between the connecting piece and the housing.
  • a circumferential groove is provided in the connection openings be in which the sealing ring engages or in which it is arranged is. However, this is not absolutely necessary. With a smooth inner wall, too sufficient sealing of the sealing ring.
  • Each connecting piece preferably has an engagement recess in which the clamping plate engages.
  • a recess is relatively easy to produce, for example by milling or turning. If the clamping plate engages in the engagement recess, then it secures the connecting piece against slip out of the connection opening. This is a relatively simple measure to the connector and to reliably connect the housing to one another.
  • the clamping plate preferably has a first section with a width that is the distance between the two connecting pieces plus the depth of the engagement recesses corresponds, and with a second section a larger width, the transition from the first Section to the second section in an arc runs.
  • the first section With the first section, the clamping plate be inserted between the two connecting pieces.
  • the second section in particular the arch, comprises then the connecting piece over a small circumferential section on the side from which the clamping plate is inserted becomes. This improved the holding force.
  • This Protective housing has several advantages. Firstly, generated it is a pleasing appearance. You can from the outside no longer recognize the tensioning device. The tensioning device is protected from pollution. Furthermore the risk that mechanical Influences from outside to damage the clamping device, the connection piece or the housing in the area of the connection openings.
